Monday’s rainfall exceeds Ondoy, last year’s Habagat

Project Nationwide Operational Assessment of Hazards (NOAH) of the Department of Science and Technology’s Philippine Atmospheric, Geophysical and Astronomical Services Administration (DOST-PAGASA) said on Tuesday that the amount of rainfall is worse compared to those spawned by typhoon Ondoy in 2009, and the southwest monsoon rains in 2012.

Dr. Mahar Lagmay, Project NOAH executive director, said Monday’s rainfall that amounted to 600 mm in 24 hours had exceeded Ondoy’s amount of rainfall of 455 millimeters in 24 hours, and last year’s habagat or monsoon rains of 472 mm in 24 hours.

Citing the accumulation map of the University of the Philippines-National Institute of Geological Sciences, Lagmay said 600 mm of rains dumped Cavite, Pampanga, Bataan, Zambales and Manila Bay.

The all-time record high rainfall was brought about by the southwest monsoon enhanced by Maring.

Lagmay said the southern portion of Metro Manila had received more amount of rainfall than in any other part of the metro.

Meanwhile, Pagasa also said that Maring will continue to enhance the southwest monsoon that will bring moderate to heavy rainshowers and thunderstorms over Luzon and Western Visayas. PNA
